you are asked to find the propulsion performance of your full-scale ship. Assigned ships were handed in the first part of the project. Students will work in the same groups, as assigned earlier. In this project, you are expected to design a propulsion system using Wageningen B-Series propeller database. At the end of the project, you need to hand in the following for your ship at the design speed: Total resistance coefficient, C_(T) Open-water propeller efficiency, eta_(0) Hull efficiency, eta_(H) Propeller rotation rate, n Advance coefficient, J Thrust coefficient, K_(T) Effective power, P_(E) Torque coefficient, K_(Q) Propeller thrust power, P_(T) Delivered power to the propeller, P_(D) You will need the wake fraction w and the thrust deduction factor t while calculating the interactions between the ship hull and the propeller. For these, use the following empirical formula: You will need the following details of your ship for your calculations:

What is a key difference between the Cutlip, Center, and Broom model of public relations and the Hunt and Grunig model? A. The Cutlip, Center, and Broom model focuses on the roles of the organization, whereas the Hunt and Grunig model focuses on the multiple roles of the individual. B. The Cutlip, Center, and Broom model focuses on the individual, whereas the Hunt and Grunig model focuses on general approaches to the practice of public relations. C. The Cutlip, Center, and Broom model focuses on the managerial roles, whereas the Hunt and Grunig model focuses on the public reception. D. The Cutlip, Center, and Broom model focuses on the public, whereas the Hunt and Grunig model focuses on the relations.

Question 4 (20 marks) The Department of Economics commissioned by the Government, intends to provide insight on the impact of human capital, brain drain, corruption and Foreign Direct Investment (FDI) on productivity. You estimated the following model. The regression results are provided below. Here productivity is the dependent variable. Method: Least Squares \table[[Variable,Coefficient Std. Error],[,,],[human capital,0.55543,0.1537],[corruption,-0.22835,0.0467],[brain drain,-0.98720,2.1208],[FDI,0.29996,1.5144],[,,]] a) All other factors being equal, test the hypothesis that corruption has no effect on producitivty in Jamaica? (7 marks) b) All other factors being equal, test the hypothesis that braindrain decreases productivity.
